Search button not working

I’m using Twenty Fourteen theme in my site http://www.camminandomontievalli.it (Hosting Linux).
Search button doesn’t work (i click it but it happens nothing). I have the same problem with my mobile and in this case I can’t use main menu too. In fact even the button to the right of the search button doesn’t work.
I don’t use Minify.
How could i fix this problem?

You have a lot of various javascripts being loaded all over the place in the header and footer.

The problem is one of those scripts either in the footer or the footer widget area is not being loaded correctly and therefore rendering the functions.js to be output incorrectly.

Take a look at your site’s source code and you’ll see that this code<script type='text/javascript' src='http://www.camminandomontievalli.it/wp-content/themes/twentyfourteen/js/functions.js?ver=20131209'></script> is not rendered correctly.

I followed your suggestion: I analyzed all my plugins and widgets that generate javascripts calls. I found the culprit!! It was the Hitstats counter. I used the same script code during the last 4 years. But now Hitstats standard javascripts countetr’s code is changed. I copied and paste the new one in my widget. Now hitstats’counter is running and TWENTYFOURTEEN’S SEARCH BUTTON IS RUNNING!

In the future if you face any similar type of issue then you can just try on your development site deactivating all other plugins and using default WordPress theme like Twenty Twelve as displayed in the flowchart on the following page to know which theme/ plugin is conflicting if any.

If the above solution doesn’t help then try removing any code added in widgets, post / page etc.

I was wondering if any of you know how to change the linking area of the search button within the Twenty Twelve theme, as mine appears to only link in corners of the button and I’d like to make it the entire area.
